Which type of routers exchange VPNv4 routes?
- P router
- P and PE routers
- PE router
- CE router
Explanation: In an MPLS L3 VPN architecture, PE routers are the only devices that exchange VPNv4/VPNv6 routes. They do so via MP-IBGP sessions with other PE routers. P routers (provider core routers) do not carry VPN routes and only maintain reachability for the core provider network via an IGP. CE routers only handle standard IPv4/IPv6 prefixes.
